Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The present invention will be described in detail below with reference to the accompanying drawings: of the present invention a kind of for adjustable spiral shell shown in Fig. 1
Oil distributor on the axis of paddle is revolved, it mainly includes oil distribution shaft 1, revolving sleeve 2, positioning pin 3, rotating seal ring 4, matches scraper ring 5, hydraulic control list
To valve 6, feedback rod 7, feedback loop 8, stop pin 9, support 10；It is characterized in that the revolving sleeve 2 is installed on the inner hole of oil distribution shaft 1
In, and the axial position of revolving sleeve 2 Yu oil distribution shaft 1 is controlled by positioning pin 3,2 front end of revolving sleeve sets that there are two hydraulic controls
Check valve 6, it is described to be sleeved on oil distribution shaft 1 with scraper ring 5, and float and arrange with scraper ring 5, it can prevent with scraper ring 5 and oil distribution shaft 1
It kills, described to be mounted with to prevent the rotating seal ring 4 of hydraulic oil seepage with 5 both ends of scraper ring, the bracket 10 is fixed on hull knot
On structure, ensure not generating rotation and axial movement with scraper ring 5 by stop pin 9；1 front end of oil distribution shaft and gear-box export
Axis or intermediate shaft flange are connected, and rear end is connected by sleeve or flange form hydrocoupling with paddle shaft or stern tube shaft；Described is anti-
Feedback 7 front end of bar is connected with feedback loop 8, and rear end is connected by the inner oil tube of paddle shaft mesoporous with the oil cylinder piston of propeller hub.It is described to match oil
Tri- mouths of A, B, C, A, B mouthful of leakage of oil self-lubricate oil distribution shaft 1 and the slidingsurface for matching scraper ring 5 are additionally provided on circle 5, remaining
Fuel tank is returned to by C mouthfuls, the reversing and ahead running of adjustable propeller are controlled by A, B mouthfuls of two-way high pressure oils, and feed back by screw pitch
Mechanism obtains current screw pitch and is transmitted to remote control system in time, and pitch feedback mechanism, feedback mechanism are installed in the rear end of the oil distribution shaft 1
Using nonlinear transducer, hydraulically-controlled one-way valve is installed in the revolving sleeve 2, hydraulic control one-way valve is the formula that is threaded into, described with oil
It encloses 5 inner holes and has inlayed bidery metal, improve the service life of oil distribution shaft 1.
The present invention is because two hydraulic control one-way valves 6 are arranged in 2 front end of revolving sleeve, after roll adjustment, with regard to the two-way oil circuit of locking,
It, can even if under the effect of biggish blade resultant moment screw pitch can also stablized in the location of instruction because hydraulic oil is incompressible
The high defect of angle of pitch hunting frequency is generated to eliminate existing tuning for Controllable Pitch Propeller, guarantees that propulsion device runnability is good, eliminates host
The hidden danger that may be overloaded, while reducing the abrasion of each moving parts of distance adjustor, extend the service life of equipment.Or navigation way
In encounter hydraulic system fault, because be provided with hydraulic control one-way valve 6, lockked oil circuit, be just avoided that screw pitch change, guarantee safety boat
Row.
Because generalling use sliding bearing in shafting, oil distribution shaft 1 is beated larger when movement, therefore is used and floated arrangement with scraper ring 5,
It efficiently solves with scraper ring 5 and the friction burn phenomenon of oil distribution shaft 1.
Embodiment: the invention mainly comprises oil distribution shaft, revolving sleeve, positioning pin, rotating seal ring, match scraper ring, fluid-control one-way
Valve, feedback rod, feedback loop, stop pin, support.It feeds back rod rear end and passes through the oil cylinder piston phase of the inner oil tube and propeller hub of paddle shaft mesoporous
Even, high pressure oil enters from A mouthfuls, enters propeller hub oil cylinder back oil pocket by hydraulic control one-way valve, feedback rod, inner oil tube, pushes oil cylinder living
Plug Forward, and then the rotation of blade positive direction is driven by crank mechanism inside propeller hub, so that ship is advanced；Conversely, high pressure oil is from B mouthfuls
Into, propeller hub oil cylinder front oil pocket is entered by hydraulic control one-way valve, oil distribution shaft mesoporous, paddle shaft mesoporous, oil cylinder piston is pushed to move back, into
And the rotation of blade opposite direction is driven by crank mechanism inside propeller hub, retreat ship.Since inner oil tube one end is fixed on propeller hub
Oil cylinder piston on, so inner oil tube also moves therewith；And the inner oil tube other end is connected with feedback rod, inner oil tube moves forward and backward
When, the feedback loop in pitch feedback mechanism is moved with feedback rod, and the sliding block on feedback loop drives non-linear screw pitch sensor
Rotation, while pointer shows the current angle of pitch, and is sent to remote control system.With A, B mouthfuls of leakage of oil self-lubricates on scraper ring with oil
Axis and the slidingsurface for matching scraper ring, remaining returns to fuel tank by C mouthfuls, while having taken away heat.
